Speed Governor Dead Band

Speed Governor Dead Band and its Effect on AGC: The effect of the Speed Governor Dead Band is that for a given position of the governor control valves, an increase/decrease in speed can occur before the position of the valve changes. The governor dead-band can materially affect the system response. In AGC studies, the dead-band […]

Appropriate Generation Rate Constraint

Appropriate Generation Rate Constraint: The Load frequency Control with Appropriate Generation Rate Constraint problem discussed so far does not consider the effect of the restrictions on the rate of change of power generation. In power systems having steam plants, power generation can change only at a specified maximum rate. The Appropriate Generation Rate Constraint (from […]

Automatic Voltage Control

Automatic Voltage Control: Automatic Voltage Control – Figure 8.20 gives the schematic diagram of an automatic voltage regulator of a generator. It basically consists of a main exciter which excites the alternator field to control the output voltage. The exciter field is automatically controlled through error e = Vref – VT suitably amplified through voltage […]
